AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to Hartzell Propeller Inc.

Model HC–E4A–3(A,I) propellers. This

action requires replacing propeller blade

counterweight clamp bolts with

improved bolts. This amendment is

prompted by reports of a manufacturing

defect in the counterweight clamp bolts

that resulted in the blade counterweight

separating and causing damage to the

propeller. The actions specified in this

AD are intended to prevent

counterweight clamp bolt failure, which

can result in propeller blade

counterweight separation and damage to

the propeller and aircraft.

DATES: Effective February 12, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of February

12, 1998.

Comments for inclusion in the Rules

Docket must be received on or before

March 30, 1998.

SUPPLEMENTARY INFORMATION: The

Federal Aviation Administration (FAA)

has received a report that a Hartzell

Propeller Inc. Model HC–E4A–3(A,I)

propeller blade counterweight clamp

bolt broke, the propeller blade

counterweight separated in flight and

damaged the adjacent propeller blade

(about 12 inches from the hub). The

investigation revealed that the propeller

blade counterweight clamp bolt failure

was caused by a manufacturing defect

known as liquid metal embrittlement.

The manufacturer has informed the

FAA that all propellers operated on

aircraft of U.S. registry have

accomplished the required actions, and,

therefore, are no longer affected by this

unsafe condition. This AD, then, is

necessary to require accomplishment of

the required actions for propellers

installed on aircraft currently of foreign

registry that may some day be imported

into the U.S. Accordingly, the FAA has

determined that notice and prior

opportunity for comment are

unnecessary and good cause exists for

making this amendment effective in less

than 30 days. This condition, if not

corrected, could result in counterweight

clamp bolt failure, which can result in

propeller blade counterweight

separation and damage to the propeller

and aircraft.

The FAA has reviewed and approved

the technical contents of Hartzell

Propeller Inc. Service Bulletin (ASB)

No. HC–ASB–61–219, Revision 1, dated

July 2, 1996, that describes procedures

for replacing propeller blade

counterweight clamp bolts with

improved bolts.

Since an unsafe condition has been

identified that is likely to exist or

develop on other propellers of the same

type design, this AD is being issued to

prevent counterweight clamp bolt

failure. This AD requires replacing

propeller blade counterweight clamp

bolts with improved bolts. The actions

are required to be accomplished in

accordance with the SB described

previously.

Since a situation exists that requires

the immediate adoption of this

regulation, it is found that notice and

opportunity for prior public comment

hereon are impracticable, and that good

cause exists for making this amendment

effective in less than 30 days.

Comments Invited

Although this action is in the form of

a final rule that involves requirements

affecting flight safety and, thus, was not

preceded by notice and an opportunity

for public comment, comments are

invited on this rule. Interested persons

are invited to comment on this rule by

submitting such written data, views, or

arguments as they may desire.

Communications should identify the

Rules Docket number and be submitted

in triplicate to the address specified

under the caption ADDRESSES. All

communications received on or before

the closing date for comments will be

considered, and this rule may be

amended in light of the comments

received. Factual information that

supports the commenter’s ideas and

suggestions is extremely helpful in

evaluating the effectiveness of the AD

action and determining whether

additional rulemaking action would be

needed.
Federal Register / Vol. 63, No. 18 /Wednesday, January 28, 1998 /Rules and Regulations 4161

Comments are specifically invited on

the overall regulatory, economic,

environmental, and energy aspects of

the rule that might suggest a need to

modify the rule. All comments

submitted will be available, both before

and after the closing date for comments,

in the Rules Docket for examination by

interested persons. A report that

summarizes each FAA-public contact

concerned with the substance of this AD

will be filed in the Rules Docket.

Commenters wishing the FAA to

acknowledge receipt of their comments

submitted in response to this notice

must submit a self-addressed, stamped

postcard on which the following

statement is made: ‘‘Comments to

Docket Number 97–ANE–35–AD.’’ The

postcard will be date stamped and

returned to the commenter.

The regulations adopted herein will

not have substantial direct effects on the

States, on the relationship between the

national government and the States, or

on the distribution of power and

responsibilities among the various

levels of government. Therefore, in

accordance with Executive Order 12612,

it is determined that this final rule does

not have sufficient federalism

implications to warrant the preparation

of a Federalism Assessment.

The FAA has determined that this

regulation is an emergency regulation

that must be issued immediately to

correct an unsafe condition in aircraft,

and is not a ‘‘significant regulatory

action’’ under Executive Order 12866. It

has been determined further that this

action involves an emergency regulation

under DOT Regulatory Policies and

Procedures (44 FR 11034, February 26,

1979). If it is determined that this

emergency regulation otherwise would

be significant under DOT Regulatory

Policies and Procedures, a final

regulatory evaluation will be prepared

and placed in the Rules Docket. A copy

of it, if filed, may be obtained from the

Rules Docket at the location provided

under the caption ADDRESSES.

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to all Dassault Model

Mystere Falcon 200 series airplanes,

that requires reducing the life limit of

the polyurethane foam used in the

fuselage fuel tanks. This amendment is

prompted by issuance of mandatory

continuing airworthiness information by

a foreign civil airworthiness authority.

The actions specified by this AD are

intended to ensure replacement of the

polyurethane foam in the fuselage fuel

tanks when it has reached its maximum

life limit; polyurethane foam that is not

replaced in a timely manner could

result in fuel contamination or
